If you take a trait that "combines" with traits from other branches or even spheres, does the newly combined trait still count as part of the original branch for stacking bonuses?
Say you have a Biest that that takes: Bor - Regional Affinity, chooses caverns, then chooses the Cavern Strength+1 then takes Bor T2: Greater Bor: Strength+1 and SIze +1.
Normally (if I have this right) a Cavern trait wouldn't stack with a Bor trait, but since you did regional affinity, the combined trait is treated as a T1 Bor trait allowing you to get a total bonus of Strength+2
